ROSI™ is our gemologist-built AI that scores each diamond on light performance, structural integrity, and real-world beauty. Every center stone we source for the Peggy is graded 90/100 or higher.
“I worked with the team for three weeks. They guided me through the diamond, the metal, the proportions — every detail. The day it arrived, I knew she’d say yes. She did. Twice.”
“We chose the Lumère because it lets the diamond breathe. The center stone is a 1.8ct ROSI™-scored 96 — it sparkles like crazy. The platinum band is comfortable for everyday wear.”
“I priced this against three other jewelers. RockHer beat all of them on diamond quality at the same price point. The made-to-order timeline was exactly 9 business days. Communication was perfect.”
The Select Edition
Searching thousands of certificates is work, and the fear of choosing the wrong diamond is real. The Select edition of this design lifts both off your shoulders. Our gemologists evaluated the certified lab diamonds suited to this setting and chose one worth standing behind, graded for cut, brilliance, and character, then verified through ROSI™, our gemological intelligence. One confident price, the diamond included, made to order in our Los Angeles atelier. One click and the deciding is done.
